DESCRIPTION The Raspberry Pi GPIO Hat is a printed circuit board that fits directly onto the Raspberry Pi's 40-pin header, providing additional GPIO (General Purpose Input/Output) pins. The hat is designed based on the Raspberry Pi 40-pin design, making it easy to use. The hat leads out all GPIO function pins and can be used to test whether all pin functions are normal. It can be used as a test board to check if all pins of the Raspberry Pi are working properly. As an expansion board, the module includes LED and basic functions, making it easy for beginners to get started with Raspberry Pi. The onboard AD/DA chip can be used as a sensor expansion board to read ADC signals or to send out DAC signals. The Raspberry Pi GPIO Hat also includes an onboard industrial wiring terminal female port, which has interface definition stickers for a more beautiful and practical setup. With these features, the Raspberry Pi GPIO Hat is a convenient and versatile tool for Raspberry Pi users to expand their projects and explore new possibilities.
